Subject: Re: AIR-X ALERT
Cc: techdiver@terra.net
Don't presume that potential Air-X problems are limited to above the water
line. Another cautionary insight photographers especially may like to note.

I and two other local divers bought Air-Xs from the same batch. Two
(including mine) have 
experienced no problems in the last 18 months. The third owner however has a
different 
experience.

He had his wrist unit replaced twice. Each of them died inexplicably, but a
recent incident provides a clue. While diving in PNG, with his ever present
Nikonos RS-AF with dual SB-104 (?) strobes, one strobe leaked causing it to
cycle and fire repeatedly. Simultaneously his Air-X wrist unit blanked out.
One hour after completion of the dive the unit reset itself. One can
speculate that each wrist unit died in the same fashion.

This diver is presently in Europe and I couldn't contact him for further
info. So I'm also unable to provide any third hand comments from the
manufacturer (probably a good thing).

I won't draw anything definitive from this but I am now a believer that
reliance on dive computers is indeed Strokery. Failure of these gadgets
isn't as remote a possibility as you might like to think.
